Hi I'm connecting an external monitor to my macbook pro and am experiencing regular vertical lines throughout the external screen. I've tried DVI-D and VGA. I've tried changing resolutions. I have taken a screen shot of the monitor but this screen shot shows a clear image. Attached is a picture of what it looks like. Hard to spot as taken with my isight. (Ignore the cable hanging down). Please help me out! Thanks
What version of the mbp do you have? Could be the graphics card going? Or soemthing buggy with the DVI port?
Are you sure it's the graphics card, because I took a screen capture of the external monitor, and that screen capture seemed okay, so surely what the graphics card is outputting is fine? Hopefully I'm wrong, because I really like this monitor!
Hmmm, what monitor is it. It's likely not the entire GPU then - could be the mini-DP (i think that's what the macbooks have) or the cable or the converter. I would check all your connections first, then move the monitor to another computer and see if it gets the same results and from there - IF Monitor is good on another computer with same cable: - Likely an error either with adapter/cable or video slot on MB IF Monitor is bad on another computer: - The monitor is toast Hope this helps!
My new MBP does this as well. It's a dual screen setup. I opened a app and dragged it off the right side of the MBP screen and it showed up on my monitor
Can you test with a different cable on that other computer? It seems it may be a monitor issue - what monitor is it?
No offence mate but I don't think you really understood the issue I'm having. I know what a dual screen set up is. I'm having issues with the actual display. Thanks for your help anyway.
